I have a couple of suggestions regarding the ojGantt module.
I have made the changes myself but I would love it to be a standard feature.
The summary bars I believe should look more as they do in Oracle Primavera P6.
The standard summary bar is also so thin it is hard to click on them.
The relationship lines should bend up/down asap after the activity and not be drawn over the text, as is the standard behavior.
Thanks for the feedback. It's very much appreciated when the community gets involved.
No guarantees on getting the features implemented, but I will file internal Enhancement Request(ER)s for these and we'll see what can be done.
